Figure 2.

Elastic ratio as a function of head bead size b for w_c = 1.6σ (Systems 1–3, 8, 9, 10, 11, and 12 from Table 2). The straight line is a fit to the data points. (Inset) Definitions of the distance of inextension, z₀; the bead sizes b and b_t; and the geometric curvature radius R₀ ≃ 2σ/(b/b_t − 1). The lateral stress profile ${\Sigma }_0$ (z) of the Cooke model is also indicated above the sketched model lipid.
